No Cats, No Syms, No CEL????

Hey fellas,

I've had the catless mids on the truck for 5 days now with no syms on the O2 sensors and I have not gotten a Check Engine Light??? Is this normal? Should I be worried?

You won't with the performance pcm. It's for offroad use ony....

yea, DC was kind enough to sell me those un-needed simms as well.

Which pcm is that? Dodge, DC, Boomer ? Shit those sims are what $150, $200?

It says DC in his signature. . .

I just called and spoke with Tony at DC Performance, and asked Boomer the same question and both of them had the same response. The code will show up as soon as the computer is finished learning.

I just did the syms at the same time as the mid pipes, and I have not gotten a code from it.

That how my truck is, the syms aren't on yet no codes, but I expect them any day now...

OK DC, Boomer etc.....is it possible to program the flash to not throw codes?

My CEL just came on last night after roughly 50 miles on the new computer. Time to put on the syms!!! Code is P0420.

 

[turbo_neon]

I was just informed that it takes 50 miles before it comes on!

CEL's are pure Bliss!

Maybe on the 06's :dontknow: mine came on immediately after swapping in my mids...
